Sensor technology along with advanced equipment improves the ability for input efficient farming in the
environment friendly way.The ultimate goal of sensortechnology in agriculture is to enable farmers and farm
managers to analyse variations in field conditions across the growing season. Soil sensing techniques to assess are being developed as an alternative to tedious manual soil sampling and laboratory testing. A tractor mounted sampler collects a required quantity of soil sample from the field and automatically transfer it for analysis.Major soil nutrient/ properties such as N, P, K, Na, pH etc. measurement with specific site can be done by using ISE
&VNIRreflectance spectroscopy with the help of DGPS tracking system to measure the accurate site location to
collect samples. The site specific soil nutrient value can be recorded in the computer. A DGPSbased on-the-go soil nutrient measurement system measuresthe soil nutrient in real time. The proposed system will have capability to store sample location & nutrient properties of soil, so that the data can be analysed for variable rate fertilizer application.
